in this study, physical vapor deposition (pvd) ti-cr-n coatings were deposited at two different temperatures100 and 400ºc on hardened and tempered tool steel substrates. the influence of the applied deposition temperature on the physical and mechanical properties of coatings such as roughness, thickness, phase composition, hardness and young’s modulus were evaluated. phase compositions were stu...

Electrospinning is a process by which fibers with micron to nanometer diameters can be obtained from an electrostatically driven jet of polymer solution. These fibers have a high surface area to volume ratio, which have numerous applications in biomedical implants such as total hip implant, dental implant. The present study is based on the hypothesis that the differences of the surface properti...

Ti-6Al-4V alloys consisting of α-Ti grains and intergranular β-Ti islands were nitrided at 850°C for 1 to 12 h under a nitrogen pressure of 1 Pa. With increasing nitriding time, the Ti-N compound layer became thicker, and the α-Ti diffusion zone containing dissolved nitrogen became wider. In the Ti-N compound layer, the initially formed Ti2N became TiN as the nitriding progressed. The nitride l...

The strongly spin-momentum coupled electronic states in topological insulators (TI) have been extensively pursued to realize efficient magnetic switching. However, previous studies show a large discrepancy of the charge-spin conversion efficiency. Moreover, current-induced magnetic switching with TI can only be observed at cryogenic temperatures. We report spin-orbit torque switching in a TI-fe...

PURPOSE Texture indices (TI) calculated from 18F-FDG PET tumor images show promise for predicting response to therapy and survival. Their calculation involves a resampling of standardized uptake values (SUV) within the tumor. This resampling can be performed differently and significantly impacts the TI values. Our aim was to investigate how the resampling approach affects the ability of TI to r...

Tonic immobility (TI) is an innate defensive behavior that can be elicited by physical restriction and postural inversion and is characterized by a profound and temporary state of akinesis. Our previous studies demonstrated that the stimulation of serotonin receptors in the dorsal raphe nucleus (DRN) appears to be biphasic during TI responses in guinea pigs (Cavia porcellus). Serotonin released...

For the deposition of hard layers on hard metals from the gas phase in the systems Ti-C-B, Ti-N-B, Ti-V-C-0, Ti-Zr-C, Ti-C-N, Ti-C, B-C and Si-C at selected deposition conditions the existence of oscillations was established, which result in a lamellar structure of the layers. As shown by Auger-Spectroscopic analyses the composition of the lamellas changes alternately. Reasons for the lamellar ...

Let T be a unit equilateral triangle, and T1, . . . , Tn be n equilateral triangles that cover T and satisfy the following two conditions: (i) Ti has side length ti (0 < ti < 1); (ii) Ti is placed with each side parallel to a side of T . We prove a conjecture of Zhang and Fan asserting that any covering that meets the above two conditions (i) and (ii) satisfies ∑n i=1 ti ≥ 2. We also show that ...

We used first-principle simulation methods to generate amorphous TiO2 (a-TiO2) models and obtained chemically-ordered amorphous networks. We analyzed the structural and the electronic properties of the resulting computationally generated structures. We propose that two peaks found in the Ti-Ti pair correlation correspond to the edge-sharing and the corner-sharing Ti-Ti pairs. Resulting coordina...

pharmacy benefit managers (PBMs) and health plans to pursue various cost-control methods and interventions, including therapeutic interchange (TI). The practice of TI relies on the conversion of one drug to a different drug within the same therapeutic class to reduce the cost of drug therapy without compromising therapeutic efficacy or safety. More than 50% of employers reported the use of TI i...
